IMPROVEMENT IN WAXING DEVICES FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 208,679, dated OctoberR, 1878' application filed January 3, 1879.

To all whom it may concern:

Be it known that I, WILLIAM S. HADAWAY, of Ghiltonville, in the countyof Plymouth and State of Massachusetts, have invented a new and ImprovedThread-Waxer for SewingMachines, of which the following is aspecification:

I11 the accompanying drawing, Figure 1 represents a verticallongitudinal section of my improved thread-waxin g device forsewingmachines, and Fig. 2 is an end elevation of the same.

Similar letters of reference indicate corresponding parts.

This invention is intended to furnish for power-operated sewing-machinesan improved thread-waxing device that can be easily adjusted for(.litterently-sized threads, and that may be easily regulated for thequantity of wax to be used, so as to save a great portion of the waxhitherto wasted.

The wax-stripping parts of the present wax ing devices are made ofrubber disks placed on a pin and adjusted by a screw. They areobjectionable, as the thread wears them out very soon, especially whenused in the sewingmachines that are driven by steam and worked at arapid rate of speed. The wearing out of the disks requires constantadjustment, and causes the loss of a large quantity of wax that daubsthe machine and makes it disagreeable for the operator.

The invention will first be described in connection with the 'drawing,and then pointed out in the claim.

Referring to the drawing, A represents a tank or receptacle for theliquid wax, to one end of which is attached an upright post or plate,13, that carries at its upper horizontallybent end an angular arm, 0,that is attached to the end of postB and acted upon by aband or otherspring, a. A set-screw, I), bears on the upper part of the arm 0, so asto raise or lower the bottom end, as required.

To the lower end of arm 0 is hinged a plate, 0, that slides along theupright post B, being guided by side flanges, d, of the same.

The post B has a perforation, c, with V- shaped lower part for thepassage of the thread, the sliding plate 0 having a similar V-shaped butinverted notch or recess, 0, that forms, jointly with the V-shaped notchb, an opening for the thread. This opening may be readily adjusted forany size of thread by the set-screw b, and also the quantity of waxregulated by the notched plates, so that only a quantity suffioient towax the thread may pass through the opening with the same.

The sliding plate 0 secures an even bearing on the post B as well as onthe thread, and allows, also, knots and bunches to pass through withoutdifl'iculty.

A wire spring-arm, 1), is attached to the tank A and bent down so as toengage by its hook-shaped end the thread, and immerse the same into theliquid wax.

A coil, f, bent at the upper part of the dcpressor, imparts the requiredspring to the arm.

The thread, in passing through the tank and the notched plates, takes upa uniform quantity of wax, prevents the daubing of the work and of themachine, and admits a cleaner working of the sewing-machine by theoperator.

Having thusdescribed my invention, I claim as new and desire to secureby Letters Patent- In a threadwvaxing device, the combination of tank A,upright post B, adjustable and spring-acted arm 0, having hingedslide-plate C, the post B, and slide-plate 0, having V- shaped recessesfor passage of thread, substantially as specified.
